Sub-20 nm spin textures with arbitrary topological charge stabilized by higher-order interactions
Zhen Sun, Shiwei Zhu, Moritz A. Goerzen +3
Topological magnetization textures play a central role in modern magnetism. For many applications, spin textures with different topological charges in the same system are parti…
Finite-temperature phase transitions across spin symmetries in two-dimensional magnets
Chen Chen, Moritz A. Goerzen, Megha Arya +3
Recent advances in intrinsic two-dimensional (2D) magnets have created a need for a unified understanding of finite-temperature phase transitions across different spin-symmetry cla…
Extended saddle points govern long-lived antiskyrmions
Megha Arya, Moritz A. Goerzen, Lionel Calmels +4
Achieving long-lived nanoscale magnetic solitons remains a central challenge, as their lifetimes typically decrease rapidly with temperature. Here, we demonstrate that anisotropic…
A new skyrmion topological transition driven by higher-order exchange interactions in Janus MnSeTe
Megha Arya, Moritz A. Goerzen, Lionel Calmels +4
Two-dimensional (2D) van der Waals magnets offer a promising platform for pushing skyrmion technology to the single-layer limit with high tunability. While Dzyaloshinskii-Moriya in…
Rashba and Dresselhaus effects in doped methylammonium lead halide perovskite MAPbI
Megha Arya, Preeti Bhumla, Sajjan Sheoran +2
Inorganic-organic lead halide perovskites, particularly methylammonium lead halide (MAPbI) perovskite, is perceived to be a promising material for optoelectronics and spintroni…
